Ok... I really need a high speed spindle machine that is bigger, faster

nicely, but it definitely does not have a high speed spindle. Not even
close. I've played with the idea of just using a router on it like I did
the Taig, but then its kind of a headache to deal with switching spindles
in
control. No horrible, but not great. I have not found a speed
multiplier I
can afford so I was thinking about making my own belt drive spindle with
pulley's to multiply speed, and then just mount it with a router-esque
style
spindle mount on the quill of the Hurco. Yeah, it's a lot of work, but
with
some planning I would not have to do any controler changes when going
from
one spindle to the other. Just load a different machine profile
depending
on which spindle I planned to use. This leaves coolant spray. At
25K-35K
RPM even a 1/32" cuter throws coolant everywhere.

Are you sure of this statement?

Well, my router(s) turns upto 35K (actually a little faster no load -
checked with an optical tach) and coolant hits all four walls of the
enclosure. Well three. The front is a clear plastic shower curtain until I
get around to making a plexiglass door. It hits the sides solidly upto
about a foot above the table at over a foot away from the cutter in all
directions. Not a solid stream, but some spray hits every surface of the
enclosure including the roof. You might argue that the air from the router
fan is part of the problem, but the net result is the same. Most of my
cutting is with larger than 1/32", but it throws coolant around too.

Or were you arguing that what I am using isn't really coolant? LOL. Or the
semantics of the word "everywhere" since you probably haven't felt any spray
from my machine(s). ROFL.
